 AGREEMENT: 
  
 NOW, THEREFORE, in consideration of the foregoing and other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the parties agree as follows: 
  

	1.	Restructuring of Restated Note. The Restated Note is hereby amended and restated, in its entirety, as set forth as Exhibit A hereto and each reference to the Restated
Note is and shall refer to such promissory note as amended and restated. ATX Group agrees to execute and deliver the Restated Note, as so amended and restated, to Leininger upon the full execution hereof. 

  

	2.	Restructuring of Warrants. Effective as of the consummation (closing and funding) of a Qualified Public Offering (the “Qualified Public Offering Closing”) on
or prior to September 30, 2004: 

  

	 	(a)	ATX Group shall assume all rights and obligations of ATX under each Warrant (as amended by this Agreement). 

  

	 	(b)	Each reference in each Warrant to the term “Company” shall mean ATX Group, and each reference to the term “Common Stock” shall mean the ATX Group Common Stock.


  

	 	(c)	Each Warrant shall be exercisable for the number of shares of ATX Group Common Stock equal to the product of (A) the number of shares of ATX Common Stock that were subject to such
Warrant immediately prior to the effectiveness of the ATX Reorganization (the “Reorganization Effective Time”), multiplied by (B) the Exchange Ratio, rounded up to the nearest whole number of shares of ATX Group Common Stock.


  

	 	(d)	The “Exercise Price” under each of the March 1998 and the June 1998 Warrants shall be equal to the quotient of (x) $1.74, divided by (y) the Exchange Ratio, and shall be
subject to adjustment after the Reorganization Effective Time as provided in such Warrant (as amended by this Agreement). 

  

	 	(e)	The “Exercise Price” under the 1999 Warrant shall be equal to the quotient of (x) $4.48 divided by (y) the Exchange Ratio, and shall be subject to adjustment after the
Reorganization Effective Time as provided in such Warrant (as amended by this Agreement). 

  

 3 










	 	(f)	Subsections 9.1(a) and (b) of each Warrant shall have no force or effect with respect to any shares issued (or deemed issued) in connection with the ATX Reorganization and/or the
Qualified Public Offering, and each such subsection shall be deleted in its entirety from each Warrant effective as of the date of the Qualified Public Offering Closing (the “Qualified Public Offering Date”).


  

	3.	Limited Power of Attorney and Proxy. Each Leininger Shareholder hereby irrevocably appoints the Chief Executive Officer and Chief Financial Officer of ATX, or either of them,
as his or its, as applicable, sole and exclusive attorney and proxy, to vote and exercise all voting rights (including, without limitation, the power to execute and deliver written consents) with respect to all of the shares of capital stock that
now are or hereafter may be beneficially owned by such Leininger Shareholder, at every meeting of the shareholders of ATX, in every written consent in lieu of such meeting and in any other action needed to effect the purposes hereof, on or prior to
September 30, 2004, in favor of approval of, (a) the ATX Reorganization, pursuant to which, simultaneously with or immediately prior to, and contingent upon, the Qualified Public Offering Closing, (i) a wholly-owned subsidiary of ATX Group will
merge with and into ATX, (ii) ATX will be the surviving corporation in the merger and will become a wholly-owned subsidiary of ATX Group and (iii) all outstanding shares of capital stock and rights to purchase capital stock of ATX will be converted
into shares of capital stock and rights to purchase capital stock of ATX Group, and (b) the Qualified Public Offering, which may be at an offering price of less than $7.38 per share. Any and all prior proxies given by each Leininger Shareholder with
respect to the voting of any shares on such matters are hereby revoked and each Leininger Shareholder agrees not to grant any subsequent proxies with respect to such matters. This proxy is irrevocable, is coupled with an interest, and is granted in
consideration of ATX and ATX Group entering into this Agreement. The attorneys and proxies named above may not exercise this irrevocable proxy on any other matter except as provided above, and each Leininger Shareholder may vote his, her or its, as
applicable, shares on all other matters. Notwithstanding anything to the contrary set forth herein, if the board of directors of ATX and/or ATX Group withdraws its authority to consummate the ATX Reorganization or the Qualified Public Offering, the
proxies granted pursuant to this Section 3 shall immediately terminate and be of no further force or effect. 

  

	4.	Exchange of Stock. In connection with the ATX Reorganization, each Leininger Shareholder agrees to take all actions necessary to exchange, or cause to be exchanged, all
shares of capital stock of ATX owned or controlled by such Leininger Shareholder, for shares of ATX Group Common Stock, pursuant to the terms of the ATX Reorganization. Each Leininger Shareholder shall surrender to ATX all certificates for such
shares of capital stock of ATX, deliver all required notices, and perform all other actions required of such Leininger Shareholder to cause such exchange and all other transactions contemplated by the ATX Reorganization to be consummated.


  

	5.	Preferred Stock Financing and Note Restriction Agreements. 

  

	 	(a)	 Each Leininger Shareholder hereby forever and irrevocably waives any rights that might arise under Section 3 of the Co-Sale Agreement or Section 2 of the
Investors’ Rights Agreement as a result of or related in any way to the ATX 



  

 4 










	 	 
Reorganization, the Qualified Public Offering, or any of the transactions contemplated thereby.

Voting Agreement shall terminate in their entirety. 

  

	 	(c)	In furtherance of Section 5(b), each Leininger Shareholder hereby agrees that (i) Section 2 of the Voting Agreement is hereby amended to add the following paragraph as Section 2(b),
and the first paragraph of Section 2 shall be numbered Section 2(a): “(b) In addition to the termination provision of Section 2(a), this Agreement shall terminate and be of no further force or effect as of the consummation (closing and funding)
of a Qualified Public Offering (as hereafter defined) on or prior to September 30, 2004. “Qualified Public Offering” means an underwritten public offering of shares of common stock, par value $.01 per share, of ATX Group, Inc., a Delaware
corporation (“ATX Group”) pursuant to a registration statement under the Securities Act of 1933, as amended, which will result in aggregate gross proceeds to ATX Group and any selling stockholders of not less than $50,000,000” and
(ii) Section 9 of the Co-Sale Agreement is hereby amended to add the following paragraph as Section 9(b), and the first paragraph of Section 9 shall be numbered Section 9(a). “(b) In addition to the termination provision of Section 9(a), this
Agreement shall terminate and be of no further force or effect as of the consummation (closing and funding) of a Qualified Public Offering (as hereafter defined) on or prior to September 30, 2004. “Qualified Public Offering” means an
underwritten public offering of shares of common stock, par value $.01 per share, of ATX Group, Inc., a Delaware corporation (“ATX Group”) pursuant to a registration statement under the Securities Act of 1933, as amended, which will result
in aggregate gross proceeds to ATX Group and any selling stockholders of not less than $50,000,000.” 

  

	 	(d)	Leininger hereby agrees that effective as of the Qualified Public Offering Closing, the Note Restriction Agreement shall terminate in its entirety. 

  

	6.	Board Designation Rights. 

  

	 	(a)	Effective as of the Qualified Public Offering Closing on or prior to September 30, 2004, and continuing thereafter until such time as Leininger ceases to beneficially own, directly
or indirectly, at least 10% of the voting power of the outstanding capital stock of ATX Group, Leininger will be entitled to notify ATX Group of the name of two persons (one of whom may be Leininger himself) for recommendation to the Nominating and
Corporate Governance Committee (or any other appropriate committee) of the board of directors of ATX Group as a nominee (the “Leininger Designees”) to said board on the terms and conditions set forth in this Section 6.


  

	 	(b)	 Subject to subsection (e) below, ATX Group shall take all such action as may be required under applicable law so that, effective as of the Qualified Public Offering




  

 5 










	 	 
Date, the board of directors of ATX Group will include the Leininger Designees, and 


  

	 	(i)	if as of the Qualified Public Offering Date the board of directors of ATX Group shall be structured as a classified board, then at least one of the Leininger Designees shall be a
member of the class of directors having a term extending until the 2007 annual meeting of stockholders of ATX Group; and 

  

	 	(ii)	if as of the Qualified Public Offering Date the board of directors of ATX Group is not a classified board, then at such time as ATX’s board of directors may become classified,
at least one of the Leininger Designees shall be included in the class of directors initially elected for the longest period of time. 

  

	 	(c)	Subject to subsection (e) below, ATX Group shall cause each Leininger Designee to be submitted to the Nominating and Corporate Governance Committee (or any other appropriate
committee) of the board of directors of ATX Group for election to the board of directors of ATX Group at each annual meeting of stockholders of ATX Group at which stockholders will vote on nominees for election to the respective classes in which the
Leininger Designees are currently serving as a director (or in any action to elect directors by written consent of the stockholders to take such a vote). ATX Group will inform Leininger a reasonable time in advance of any date by which nominees must
be submitted in order to be eligible for election to the ATX Group board of directors, and if Leininger fails to provide written notice of the names of the Leininger Designees on or before such date, then the Leininger Designees previously named by
Leininger shall be deemed to be the Leininger Designees without further action by Leininger. 

  

	 	(d)	Subject to subsection (e) below, in the event that a vacancy is created on the board of directors of ATX Group at any time by the death, disability, retirement, resignation or
removal (with or without cause) of a Leininger Designee, ATX Group and the remaining directors will cause the vacancy created thereby to be filled by a new designee of Leininger as soon as possible, who is designated in the manner specified in this
Section 6, and ATX Group hereby agrees to take, or cause to be taken, at any time and from time to time, all actions necessary to accomplish the same. 

  

	 	(e)	Notwithstanding anything to the contrary set forth herein, nothing contained in this Section 6 shall require ATX Group to take any action, either now or in the future, that, in the
opinion of its board of directors, is or would reasonably by likely to be inconsistent with, conflict with, or violate (i) any applicable law, (ii) the charter or bylaws of ATX Group, or (iii) the rules and regulations of any stock exchange or
automated quotation service on which any securities of ATX Group are listed or quoted. 

  

 6 










	 	(f)	Leininger agrees, and shall cause each of his representatives (including the Leininger Designees) to agree, to hold in confidence and trust and not use or disclose any confidential
information provided to or learned by it in connection with the exercise of Leininger’s rights under this Section 6, unless otherwise required by law or if such information has become publicly available through no fault of Leininger.


  

	7.	Representations of the Leininger Shareholders. The Leininger Shareholders hereby represent and warrant to ATX and ATX Group, jointly and severally, as follows:


  

	 	(a)	Each Leininger Shareholder is the sole record owner and controls the power to vote and dispose of the number of shares and class of capital stock of ATX set forth opposite such
Leininger Shareholder’s name on Schedule B hereto. 

  

	 	(b)	Leininger is the sole beneficial and record owner of the Restated Note and each of the Warrants. Leininger has not sold, assigned or otherwise transferred any rights in the Restated

	 	(c)	Except for this Agreement, the Preferred Stock Financing Agreements, and the other agreements and instruments listed in the recitals hereto, the Leininger Shareholders do not have

 Effective as of the Qualified Public Offering Closing, the Company shall cause the following legend to be added to the face of the Restated Note and each
Warrant, or to otherwise be prominently affixed thereto:

of the other party, it being understood and agreed that (i) a merger of ATX or any successor (whether pursuant to the ATX Reorganization, for the purpose of reincorporation in another jurisdiction, or otherwise) shall not be deemed an assignment and
(ii) Leininger may assign and transfer its rights under this Agreement to one or more affiliates (including, solely for the purposes of this Section 13, Leininger’s lineal descendants, family members, family trusts and family limited
partnerships) of Leininger to which Leininger transfers capital stock of ATX (or subsequent to the ATX Reorganization, ATX Group), so long as each transferee agrees in writing to be bound by this Agreement to the same extent as Leininger. Subject to
the preceding sentence, this Agreement will be binding upon, inure to the benefit of and be enforceable by the parties and their respective heirs, personal representatives, successors and assigns.

Agreement shall be enforceable in full accordance with their terms.
